I recently bought a modern timing light with the ability to “dial in” the advance. This allows you, with a single pair of TDC marks, to understand the advance at any level of revs. Very useful for diagnosing where the distributor advance is. Not much use with a fixed distributor but when you reinstate manual advance/retard would be very handy for sorting things out. Great when sorting recalcitrant auto advance distributors too.
